PROFIBUS-DP
To insert BIS C-622 processor into the serial PROFIBUS and to connect the supply voltage
and the digital input, the cables have to be connected to the terminals of the processor. For
more details regarding the wiring see the following
. The read/write heads have to be
connected to the to terminals Head 1 and Head 2.
Ensure that the device is turned off.
Connect the "incoming" PROFIBUS cable to the PROFIBUS-DP input. Connect the "outgo-
ing" PROFIBUS cable to the PROFIBUS-DP output.
In case the processor is the last bus module in the chain, then only the incoming cable is
connected to the input.
The last bus module must terminate the bus with a resistor. In the case of the BIS C-622,
this can be realized in two different ways:
1.
Inside the unit
by closing
switch S2
(factory set to open)
The PROFIBUS output must
be closed off with a cap in order to maintain the enclosure rating.
2.
Outside the unit
in a connector. Bring out the signals VP and DGND to tie the external
termination resistors to plus.
Note:
S2 must be open!
No supply voltage
is allowed on the PROFIBUS connections!
Connect cable for the supply voltage and the digital input to terminal X1.
